‘Surge in construction’ at suspected Iranian nuclear site, analysts say, as US considers ways to strike deep underground | CNN Politics

A suspected Iranian nuclear site buried under granite has seen a flurry of construction work this year as the war with the US has transpired, according to a group of analysts who reviewed six years of satellite imagery.

Resolution criteria

This market resolves to YES if, between market creation and October 1, 2027, at 11:59 PM UTC, the United States military or the Israel Defense Forces (IDF) conduct a confirmed kinetic military strike (e.g., airstrikes, missile strikes, or drone attacks) targeting Iran’s Pickaxe Mountain underground facility (also known in Farsi as Kuh-e Kolang Gaz La, located approximately 2 kilometers south of the Natanz uranium enrichment complex).

This market resolves to NO if no such strike occurs by the deadline.

Additional Conditions and Clarifications:

• Attribution: The strike must be publicly claimed by, attributed to, or widely acknowledged by officials from the US, Israeli, or Iranian governments, or confirmed by credible international news agencies (such as Reuters, Associated Press, CNN, BBC, or The New York Times).

• Kinetic vs. Non-Kinetic: The attack must be physical and kinetic. Cyberattacks, espionage, industrial accidents, or standalone acts of covert sabotage that do not involve military-launched ordnance (such as bombs, missiles, or kamikaze drones) will not trigger a YES resolution.

• Target Identity: The target must specifically be the Pickaxe Mountain/Kuh-e Kolang Gaz La underground site itself or its immediate fortified portal/access infrastructure. Attacks targeting other parts of the main Natanz complex will not suffice unless Pickaxe Mountain is also struck.

Background

Pickaxe Mountain (Kuh-e Kolang Gaz La) is a deeply buried, heavily fortified underground tunnel complex located near Iran's Natanz uranium enrichment facility. Satellite analysis released in September 2026 by the Center for Strategic and International Studies (CSIS) indicates a significant surge in construction at the site, which analysts believe is intended to serve as a hardened shelter for Iran's nuclear program.

Because the site is buried deep beneath granite, it is exceptionally difficult to target with conventional bunker-busting bombs. The facility has become a major focal point of geopolitical tension, with US President Donald Trump and Israeli officials issuing direct threats of potential military strikes to prevent Iran from securing its advanced centrifuges and enriched material deep underground.
